An SMI file may also be a plain text subtitles file written in the SAMI (Synchronized Accessible Media Interchange) format. It contains subtitle text, timing information, and styling information. SMI files can be used to show subtitles in a variety of media players.
More Information
SMI files always include <SAMI> as their first line of text. The file then goes on to define its subtitles' margin, font, text alignment, and color.
The file's included subtitles begin at the <BODY> tag. Each line of subtitle text is paired with a <SYNC Start=> tag, which specifies when that line of text appears on-screen. Typically, SYNC Start times are written in milliseconds (so a line of text paired with <SYNC Start=3400> will appear 3400 ms into a video).
NOTE: The SAMI format was developed by Microsoft, as an extension of HTML.
How do I convert SMI subtitles to SRT subtitles?
The .SRT subtitle format is more common than the SMI format. Therefore, you might want to convert your SMI subtitles to the SRT format.
SubtitleTools.com has a converter, called Convert Subtitles to Srt, that you can use to convert SMI files to the SRT format. MConverter.eu also allows users to convert SMI files to the SRT format.
How to open an SMI file
